A common question we receive is about the meaning behind the color coding of spray nozzle tips. Those colors are not just there to look nice- they are a quick, at a glance way to identify the tip’s flow rate, so you can grab the right tip fast and keep your application rate on track.

What the Colors Actually Mean

Nozzle tips are the last stop before product leaves the sprayer, so the tip you choose affects a lot more than people think, including:

  • How much liquid comes out (flow rate)
  • How evenly it is applied
  • How well you hit your target without wasting product

To keep things simple in the real world, most manufacturers follow a widely used color system where each color lines up with a specific flow rate, usually referenced at 40 PSI. So instead of squinting at tiny stamped numbers, you can often just look at the color and know the general capacity.

Common Nozzle Tip Color Chart

Here is a typical reference for GPM at 40 PSI:

  • Orange: 0.10 GPM
  • Green: 0.15 GPM
  • Yellow: 0.20 GPM
  • Purple: 0.25 GPM
  • Blue: 0.30 GPM
  • Red: 0.40 GPM
  • Brown: 0.50 GPM
  • Gray: 0.60 GPM
  • White: 0.80 GPM

Quick tip: Flow rate changes with pressure. If you raise or lower PSI, the GPM changes too, so always reference a nozzle chart when you are dialing in rate.

Why Color Coding Matters in the Real World

Faster changes in the field

If you need to adjust your application rate, change speeds, or respond to conditions, color coding makes tip swaps quicker and more confident, with a lot less second guessing.

More accurate application

The right tip helps you avoid overapplying or underapplying, which saves money and keeps results more consistent.

Less confusion across brands

Even if you run multiple nozzle brands, the color system usually keeps things familiar, so your “red tip” still means the same general size.

Bottom Line

Nozzle tip colors are basically shorthand for nozzle size and flow rate. Once you know the system, you move faster, make fewer mistakes, and stay more consistent from one application to the next.

If you want, paste the exact nozzles you sell most (brand and style, like AIXR, TTI, Turbo TeeJet, Hypro, Arag, and so on) and I can tighten this up with a more specific chart, a few pressure notes, and a quick example showing how tip size ties into GPA at different speeds.
